RGBColor
RGBColor[r,g,b]
represents a color in the RGB color space with red, blue and green components.
RGBColor[r,g,b,a]
specifies opacity a.
RGBColor["string"]
returns a color from an HTML color name, etc.
RGBColor[color]
returns the RGB representation of color.
Details

- RGBColor is a color space defined by three additive primaries, red, green, and blue, typically used in electronic display devices.
- Red, green, and blue color intensities outside the range 0 to 1 will be clipped, as will opacities. »
- On monochrome output devices, a gray level based on the average of the color intensities is used.
- ColorConvert can be used to convert RGBColor to other color spaces.
- The alternative forms RGBColor[{r,g,b}] and RGBColor[{r,g,b,a}] can also be used. »
- In RGBColor[spec], spec can be any of the following:
-
"#rrggbb" six-digit hexadecimal "#rgb" three-digit (shorthand) hexadecimal form "#rrggbbαα" hexadecimal form with opacity "htmlcolor" HTML color color a color directive - RGBColor[color] can be used to convert any ColorQ expression to RGB.
- Style[expr,RGBColor…]] specifies that expr should be displayed with the specified color. »
- For 3D surfaces, explicit RGBColor directives define surface colors; the final shading depends on lighting and contributions from specularity and glow. »
- Glow[RGBColor[…]] specifies color independent of lighting. »
- RGBColor[r,g,b,a] is equivalent to Directive[RGBColor[r,g,b],Opacity[a]]. »
- If no opacity has been specified, RGBColor[r,g,b] is equivalent to RGBColor[r,g,b,1].
